The ARX 91 is a 9-tonne class Articulated Tandem Roller. A powerful, two-stage vibratory system – combined with drum dimensions and multiple amplitude and frequency settings – provides productivity and flexibility in both soil and asphalt applications. The varied settings enable compaction of loose sub-base materials, such as gravel, as well as asphalt lifts, including thick layers. A unique propulsion system provides the smooth starts and stops needed when working on asphalt. The machine’s high centrifugal force enables compaction goals to be met in minimal passes.

The location of the engine in the rear of the roller is another advantage. This placement helps drive vibration away from the operator and toward the compaction target. It also improves visibility and redirects heat from the operator, thereby increasing comfort. A large water tank (1000 litres) minimises the need for refills.

The machine is efficient and its electronic joystick controls are intuitive, helping even inexperienced operators succeed. A tight turning radius enables operator an improved control and manoeuvrability.
